Claim 4

The composition of claim 1 in which the liquid vehicle consists of: a. several of said halogenated hydrocarbon solvents; or b. a blend of at least one of the halogenated hydrocarbon solvents with up to 25 percent by volume of the blend of an organic solvent for said film-forming resin.

Claim 5

the balance of said composition consisting essentially of solid constituents of a. a film-forming acrylate resin which consists of a homo- or co-polymer of a lower alkyl ester of acrylic acid, methacrylic acid, ethacrylic acid, or mixture thereof, having up to and including four carbon atoms in their ester moiety with the film-forming acrylate resin amounting to between 11 and 16 percent by weight of the total of the solid constituents, and b. the balance of the solid substituents consisting essentially of i. an organic optical brightener/silica-modified rutile titanium dioxide pigment consisting essentially of at least 88 percent by weight of rutile titanium dioxide having incorporated therein between 0.1 and 0.4 percent by weight of an organic optical brightener, which essentially is a colorless fluorescent organic substance emitting visible radiation below 5,500 A upon absorbing ultraviolet radiation above 3,000 A and a balance essentially of silica, and ii. a flatting and extender pigment, which is a diatomaceous silica, in an amount between 6 and 11 percent by weight of the total of the solid constituents.
