Abstract
Abstract A one-pack type, cold-setting composition comprising (1) a copolymer of at least one Beta -ethylenically unsaturated monomer or conjugated diene monomer and at least one Alpha , Beta -ethylenically unsaturated hydroxy compound, (2) a curing agent, and (3) a organic solvent, characterized in that the above curing agent is a complex of (a) an alkyl or alkenyl titanate with (b) at least one glycol and/or (c) at least one Alpha hydroxycarboxylate or a mixture of the above (a) component with the above (b) component and/or the above (c) component, the amount of said complex being 0.1 to 5.0 moles per equivalent of the hydroxy group of the copolymer or the amount of the above mixture being such that the (a) component is present in an amount of 0.1 to 5.0 moles per equivalent of the hydroxy group of the copolymer, and the (b) and/or (c) component is present in an amount of from 0.5(m+1) to 2(m+2) moles per mole of the (a) component. The above coating composition is colorless and transparent and the cured film obtained therefrom has excellent in resistance to weathering, solvents and chemicals and also has excellent adhesion, gloss and hardness.
