Zusammenfassung: | The invention relates to a polyurethane compound. The invention provides a material, which can be light-patterned, can resistant to component heating in substrate manufacturing, can resistant to chemical treatment by using a solder resist, has a long acting insulation performance, and is soft and tough. The polyurethane compound (A) is prepared by reactions among (c) an unsaturated epoxy carboxylate compound, (d) a compound containing two hydroxyl groups and at least one carboxyl group, (e) a polyester diol compound of dicarboxylic acid with a carbon number greater than 10, and (f) a compoundcontaining two isocyanate groups; wherein the compound (c) is prepared by reactions between (b) a compound containing at least one ethylene like unsaturated group and one carboxyl group and (a) an epoxy compound (a) containing two epoxy groups. |
