PURPOSE: A composition that is obtained by adding a specific polypropylene and a specific solid resin, thus showing good tackiness for a long period of time and giving coating films of high solvent resistance. n CONSTITUTION: (A) 50W90pts.wt. of a chlorinated polypropylene which may contain up to 70wt% of an ethylene-vinyl acetate copolymer of 5W40wt% vinyl acetate content, have 10W50wt% chlorine content and 2W70 acid value based on the solid content and/or another chlorinated polypropylene of 2W150 hydroxyl value base on the solid content are combined with (B) 50W10pts.wt. of a resin which is solid at room temperature and soluble in solvents selected from aromatic, aliphatic, alicyclic hydrocarbons, ketones, esters, alcohols and chlorinated hydrocarbons and can give tackiness to component A. The component B is, e.g., 100% phenolic resin or rosin-modified phenolic resin. n COPYRIGHT: (C)1986,JPO&Japio |
