Abstract
A composition suitable for a hot melt-type white traffic paint which has good melt flowability, good thermal stability and high whiteness is prepared by blending: (A) an acid-modified hydrocarbon resin having an acid value of 0.10 to 15 obtained by oxidizing a hydrocarbon resin or reacting it with an .alpha.,.beta.-unsaturated carboxylic acid, or an ester-modified hydrocarbon resin obtained by reacting the acid-modified hydrocarbon resin with an alcohol; with (B) titanium dioxide.

A composition for a hot melt-type white traffic point comprising:
- (A)(1) 100 parts by weight of an acid-modified hydrocarbon resin having an acid value of 0.10 to 15 obtained by an oxidation of a thermoplastic hydrocarbon resin in a liquid state or by a reaction of the thermoplastic hydrocarbon resin with an .alpha.,.beta.-unsaturated carboxylic acid or anhydride thereof, said thermoplastic hydrocarbon resin being solid at room temperature having an average molecular weight of 500 to 3,000, a softening point of 60.degree. to 150.degree. C as determined by the ring ball method and a Gardner color of not greater than 10, as measured for 100% resin, or
- (2) an esterified hydrocarbon resin obtained by the reaction of said acid-modified hydrocarbon resin with an alcohol, and
- (B) 25 to 300 parts by weight of titanium dioxide.
A composition suitable for a hot melt-type white traffic paint comprising;
- (A) 100 parts by weight of an acid-modified hydrocarbon resin obtained by reacting 100 parts by weight of a hydrocarbon resin with 0.1 to 5 parts by weight of maleic anhydride, said hydrocarbon resin being obtained by polymerizing in the presence of a Friedel-Crafts catalyst, a C.sub.4 to C.sub.5 hydrocarbon fraction (having a boiling point;
- -15.degree. to 60.degree. C) obtained by thermal cracking, mainly composed of unsaturated aliphatic hydrocarbons having four to five carbon atoms in their molecules, said hydrocarbon resin having an average molecular weight of 700 to 2000, a softening point of 70.degree. to 120.degree. C as determined by the ring ball method and a Gardner color of not greater than 8, as measured for 100% resin;
- and (B) 25 to 300 parts by weight of titanium dioxide.
A hot melt-type white traffic paint comprising;
- (A) 10 to 30% by weight of an acid-modified hydrocarbon resin obtained by reacting 100 parts by weight of a hydrocarbon resin with 0.1 to 5 parts by weight of maleic anhydride, said hydrocarbon resin being obtained by polymerizing, in the presence of a Friedel-Crafts catalyst, a C.sub.4 to C.sub.5 hydrocarbon fraction (having a boiling point of -15.degree. to 60.degree. C) obtained by thermal cracking, mainly composed of unsaturated aliphatic hydrocarbons having four to five carbon atoms in their molecule, said hydrocarbon resin having an average molecular weight of 700 to 2000, a softening point of 70.degree. to 120.degree. C as determined by the ring ball method and a Gardner color or not greater than 8, as measured for 100% resin;
- (B) 5 to 30% by weight of titanium dioxide;
- (C) 40 to 75% by weight of filler;
