Claim 1
Independent Claim
118 words
A rubber tire having at least one surface coated with a composition comprised of (A) 100 parts by weight polyvinylalcohol (PVA) coating comprised of about 70 to about 90 percent PVA and, correspondingly, about 10 to about 30 percent of at least one of polyglycerol, diglycerol and glycerin plasticizer therefor; and (B) about 2.5 to about 10 parts by weight of at least one water soluble ultraviolet absorber selected from at least one of (i) a reaction product of beta-(3(2H-benzotriazol-2-yl)-4-hydroxy-5-tert-butylphenyl)-propionic acid, methylester thereof and polyethyleneglycol having a molecular weight in the range of about 200 to about 400, (ii) poly(oxy-1,2-ethanediyl) alpha(3-(3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl-1-oxopropyl)-omega-hydroxy and (iii) poly (oxy-1,2-ethanediyl), alpha-3-(3-(2H-benzotriazole-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl)-1-oxopropyl)-omega-(3-(3-(2H-benzo-triazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxyphenyl)-1-oxopropoxy) and having an ultraviolet light reflective label affixed on said coated surface.
Claim 2
Dependent Claim
