Scratch resistant top coating composition

In a pigment dispersion comprising a pigment, a dispersing agent and an organic dispersing medium, the improvement wherein the dispersing agent is the reaction product of an amino resin, an alkyd resin or an acrylic resin with a silane coupling agent, or the reaction product of both an alkyd resin or an acrylic resin and an amino resin with a silane coupling agent.

Pigment dispersion

A photocurable composition comprising a copolymer of maleic acid monoester with .alpha.-olefine compound, a polymerizable ethylenically unsaturated compound having a number average molecular weight of less than 3,000 and a boiling point of more than 100.degree. C. at a normal pressure, and a photosensitizer.

Photocurable composition comprising copolymer of maleic acid monoester

A photocurable composition comprising a copolymer of maleic acid monoester with .alpha.-olefine compound, a vinylurethane compound obtained by urethanation reaction of a polyisocyanate compound with a photopolymerizable ethylenically unsaturated alcohol having a number average molecular weight of less than 3,000 or by urethanation reaction of 1 mole of diisocyanate compound with about 1 mole of the photopolymerizable ethylenically unsaturated alcohol and about 1/m mole of m-valent alcohol (wherein m is an integer of 2 to 6) having a number average molecular weight of less than 3,000, and a photosensitizer.
