This invention relates to a graft polyolefin which is obtained by a method comprising the steps of: (a) dissolving or dispersing, in an organic solvent, an acid anhydride-modified amorphous polyolefin which comprises propylene and butene as polymerizable components, thereby preparing its solution or dispersion; (b) adding a hydroxyl group-containing radical polymerizable monomer to the solution or dispersion, and allowing the acid anhydride-modified polyolefin to react with the hydroxyl group-containing radical polymerizable monomer; and (c) effecting graft polymerization by adding at least one radical polymerizable monomer and a radical initiator. This invention also relates to a resin coating composition which contains this graft polyolefin as a solid content.

摘要:
The present invention provides: a photosensitive resin composition, which can form uniform coating films having higher coating film strength without causing surface contamination, decrease of evenness of coating films, decrease of film thickness, and coloring by decomposition in heat treatment of subsequent steps, and has good sensitivity of exposure. The photosensitive resin composition comprises a lactone-ring-containing polymer (A) as an essential component, wherein: the lactone-ring-containing polymer (A) is obtained by carrying out polymerization of comonomers and lactonization at the same time wherein the comonomers include a 2-(hydroxyalkyl)acrylate ester and an acidic-group-containing monomer; and the lactone-ring-containing polymer (A) is obtained by almost quantitatively carrying out lactonization of a 2-(hydroxyalkyl)acrylate ester structural unit.
