PURPOSE:To provide the titled compsn. which is useful as a pretreating agent for plastics and gives improved adhesion between plastics and an intercoat or a topcoat, consisting mainly of a specified modified polyolefin resin and an org. solvent. CONSTITUTION:An ethylenic hydrocarbon compd (i) [e.g., a copolymer having a glass transition temp. (thermal method) of not higher than -10 deg.C, composed of 10-60mol% ethylene and 90-40mol% of propylene] is graft-polymerized with maleic acid (anhydride) (ii) at 100-160 deg.C in the presence of a radical generating agent in an org. solvent to obtain a polyolefin resin (a) having a component (ii) content of 1-25wt%. 1-50wt% monoepoxy compd. (b) (e.g., glycidyl ester of a tertiary fatty acid) is added to the component (a) at 90-130 deg.C in the presence of a catalyst to obtain a modified polyolefin (A). the component A is blended with an org. solvent (B) (e.g., toluene). If desired, a pigment, (a dispersant), electrically conductive powder, a plasticizer, a surfactant, etc., are added thereto. |
