FOR IMMEDIATE RELEASE


                 KRONOS WORLDWIDE REPORTS FIRST QUARTER RESULTS

DALLAS,  TEXAS...May 5, 2004...Kronos Worldwide,  Inc. (NYSE:KRO) today reported
net income for the first  quarter of 2004 of $9.8  million,  or $.20 per diluted
share,  compared with income of $16.7 million, or $.34 per diluted share, in the
first quarter of 2003.

Sales of $263.3 million in the first quarter of 2004 were $10.3 million,  or 4%,
higher than the first quarter of 2003 as the favorable effect of fluctuations in
foreign  currency  exchange rates,  which increased sales by  approximately  $21
million,  more than offset the impact of lower average  selling prices for TiO2.
Despite the increase in sales,  TiO2 segment profit (see description of non-GAAP
information  below)  declined  to $26.2  million  in the first  quarter  of 2004
compared  with $34.4  million in the first  quarter of 2003 due primarily to the
lower average TiO2 selling prices.

The Company's  average selling prices in billing  currencies (which excludes the
effects  of  fluctuations  in the  value of the U.S.  dollar  relative  to other
currencies)  during  the  first  quarter  of 2004  were 4% lower  than the first
quarter  of 2003.  Expressed  in U.S.  dollars  computed  using  actual  foreign
currency exchange rates prevailing during the respective periods,  the Company's
average  selling  prices in the first  quarter  of 2004 were 4% higher  than the
first quarter of 2003.

The  Company's  TiO2 sales and  production  volumes in the first quarter of 2004
approximated its respective sales and production volumes in the first quarter of
2003, with operating rates at near full capacity in both periods. Finished goods
inventories at March 31, 2004,  which  represented  2.2 months of average sales,
were lower as compared to December 31, 2003.

Interest  expense in the first quarter of 2004  increased  $5.3 million from the
comparable  prior year period  primarily due to interest on the  Company's  $200
million 9%  long-term  note  payable to NL  Industries,  Inc.  that the  Company
distributed to NL in December 2003. In addition,  interest expense increased due
to relative changes in foreign currency exchange rates, which increased the U.S.
dollar equivalent of interest expense on the Company's  euro-denominated  Senior
Secured  Notes by  approximately  $1.1  million in the first  quarter of 2004 as
compared to the first quarter of 2003.

The Company's  effective  income tax rate in the first quarter of 2004 was lower
than the first  quarter  of 2003 due  primarily  to the  utilization  of certain
foreign  income tax  attributes  for which the benefit had not  previously  been
recognized.

The statements in this release relating to matters that are not historical facts
are  forward-looking   statements  that  represent   management's   beliefs  and
assumptions  based on  currently  available  information.  Although  the Company
believes that the expectations reflected in such forward-looking  statements are
reasonable,  it cannot give any assurances that these expectations will prove to
be correct.  Such  statements  by their  nature  involve  substantial  risks and
uncertainties  that could  significantly  impact  expected  results,  and actual
future   results  could  differ   materially   from  those   described  in  such
forward-looking  statements.  While it is not  possible to identify all factors,
the Company  continues to face many risks and  uncertainties.  Among the factors
that could cause actual future results to differ materially include, but are not
limited to:

o    Future supply and demand for the Company's products,
o    The cyclicality of certain of the Company's businesses,
o    Customer inventory levels,
o    Changes in raw material and other operating costs,
o    The possibility of labor disruptions,
o    General global economic and political conditions,
o    Competitive products and substitute products,
o    Customer and competitor strategies,
o    The impact of pricing and production decisions,
o    Competitive technology positions,
o    Fluctuations in currency exchange rates,
o    Operating interruptions,
o    The ability of the Company to renew or refinance credit facilities,
o    The ultimate  outcome of income tax audits,  tax settlement  initiatives or
     other tax controversies, and
o    Government laws and regulations and possible changes therein,
o    The ultimate resolution of pending litigation, and
o    Possible future litigation.

Should one or more of these risks  materialize  (or the  consequences  of such a
development  worsen),  or should the  underlying  assumptions  prove  incorrect,
actual results could differ  materially from those  forecasted or expected.  The
Company   disclaims  any  intention  or  obligation  to  update  or  revise  any
forward-looking statement whether as a result of new information,  future events
or otherwise.

In an effort to provide  investors  with  additional  information  regarding the
Company's results as determined by accounting  principles  generally accepted in
the  United  States of America  ("GAAP"),  the  Company  has  disclosed  certain
non-GAAP  information which the Company believes provides useful  information to
investors:

o    The Company discloses percentage changes in its average TiO2 selling prices
     in billing  currencies,  which  excludes  the  effects of foreign  currency
     translation.  The Company  believes  disclosure of such percentage  changes
     allows  investors to analyze such changes  without the impact of changes in
     foreign  currency  exchange rates,  thereby  facilitating  period-to-period
     comparisons  of relative  changes in average  selling  prices in the actual
     various  billing  currencies.   Generally,  when  the  U.S.  dollar  either
     strengthens or weakens against other  currencies,  the percentage change in
     average  selling  prices  in  billing  currencies  will be higher or lower,
     respectively,  than such percentage  changes would be using actual exchange
     rates prevailing during the respective periods.
o    The  Company  discloses  segment  profit,  which  is used by the  Company's
     management to assess the performance of the Company's TiO2 operations.  The
     Company believes  disclosure of segment profit provides useful  information
     to investors  because it allows investors to analyze the performance of the
     Company's  TiO2  operations in the same way that the  Company's  management
     assesses  performance.  The Company defines segment profit as income before
     income  taxes,  interest  expense  and  certain  general  corporate  items.
     Corporate items excluded from the  determination  of segment profit include
     corporate  expense and interest  income not  attributable  to the Company's
     TiO2 operations.

Kronos  Worldwide,  Inc. is a major  international  producer of titanium dioxide
pigments.
