摘要： A powder coating comprising a thermosetting resinous composition comprising a base resin having 2 or more oxirane groups in its molecule and a hardener for epoxy resin, which is characterized by further containing 0.5 to 10% by weight based on the base resin weight of a vinyl resin containing 1 to 10% by weight of at least one aliphatic dicarboxylic acid selected from thiomalic acid, maleic acid, fumaric acid and itaconic acid and having a number average molecular weight of 1000 to 8000 and a glass transition temperature of -40.degree. to 100.degree. C. The coating obtained is excellent in smoothness, gloss and image clarity.

摘要： A powder coating comprising, as main components. (A) a carboxyl group containing resin having a number average molecular weight of 1000-30000, an acid value of 5-200 KOH mg/g and a glass transition temp. of 20.degree.-120.degree. C., and (B) a polyglycidyl compound obtained by addition of a polyester oligomer having 2 or more carboxyl groups and a number average molecular weight of 200-1200, with an epoxy compound of the formula: ##STR1## , the ratio of carboxyl groups in (A) to glycidyl groups in (B) being, in terms of equivalent ratio, 0.5 to 2.0. This powder coating may result a coating with excellent processability, impact strength and the like and is excellent in storage stability, hardening properties either at high or low temperature and even when used a stored powder may result a coating with excellent processability.

摘要： A colored base composition comprising a dispersing amphoteric resin and pigment, said amphoteric resin being prepared by the addition or condensation reaction of an acidic resin bearing both of an electron acceptant group and a functional group and a basic resin and/or basic low molecular weight compound bearing both of an electron donative group and a functional group, the functional group located on one side of the reactants being an active hydrogen and/or active alkoxyl group and the functional group located on the other side of the reactants being a group which is reactive with said active hydrogen and/or active alkoxyl. This base composition is quite stable, compatible with various kinds of resins and pigments and capable of producing a paint composition with excellent film performance.
摘要翻译：包含分散两性树脂和颜料的着色基础组合物，所述两性树脂通过具有电子受体基团和官能团的酸性树脂的加成或缩合反应以及碱性树脂和/或碱性低分子量化合物同时具有电子给予基团和官能团，反应物一侧的官能团为活性氢和/或活性烷氧基，位于反应物另一侧的官能团为反应性基团与所述活性氢和/或活性烷氧基。该基础组合物相当稳定，与各种树脂和颜料相容，并且能够生产具有优异膜性能的涂料组合物。
