Abstract
Abstract Alkyd resins containing functional epoxides as long-chain modifying agents. The functional epoxides used are selected from the following: (a) epoxidized unsaturated fatty alcohols containing from 16 to 22 C-atoms, (b) esters of epoxidized fatty acids and monofunctional alcohols containing from 1 to 18 C-atoms, (c) epoxidized triglycerides, (d) reaction products of epoxidized triglycerides containing in the molecule epoxide groups and secondary hydroxyl groups formed by ring opening. The alkyd resins according to the invention are distinguished by particularly good weathering properties.
