Abstract
Abstract A resinous composition, which is curable by photo-irradiation even in the presence of oxygen, is prepared from (A) 2 to 60% by weight of a divalent or trivalent metal salt of an unsaturated mono- or di-carboxylic acid, (B) 98 to 40% by weight of unsaturated compound having from 0.5 to 12 polymerizable unsaturated bonds per unit molecular weight of 1000 and (C) photosensitizers. This composition is suitable for uses such as coating materials or ink binders and can produce tack free coated films. The films obtained after curing this composition are excellent in adhesive property as well as in other chemical and mechanical properties.
