ADDITIVE FOR ADHESION IMPROVEMENT RESIN AND RESIN COMPOSITION

To provide an additive for a resin which prevents deterioration in compatibility between a resin and the additive even when an addition amount is large, is excellent in solubility at room temperature to a solvent, and improves adhesion between the resin and a metal material, and a resin composition containing the additive.SOLUTION: An additive for an adhesion improvement resin is represented by the following general formula (1) and is composed of a polyalkylene glycol derivative having a triazine skeleton. In the formula (1), R represents an aromatic hydrocarbon group, and AO represents an oxyalkylene group having 2 to 4 carbon atoms; m represents an average addition molar number of an oxypropylene group and 1-40; and n represents an average addition molar number of the oxyalkylene group and is 0-40.SELECTED DRAWING: None 【課題】添加量が多い場合でも樹脂との相溶性が低下せず、溶剤に対する室温での溶解性が優れる、樹脂と金属材料間の密着性を向上させるための樹脂用添加剤、及び該添加剤を含有する樹脂組成物の提供。【解決手段】下記一般式（１）で表される、トリアジン骨格を有するポリアルキレングリコール誘導体からなる、密着性向上樹脂用添加剤。（式（１）中、Ｒは、芳香族炭化水素基を表し、ＡＯは炭素数２〜４のオキシアルキレン基を表す。ｍは、オキシプロピレン基の平均付加モル数を表し、１〜４０である。ｎは、前記オキシアルキレン基の平均付加モル数を表し、０〜４０である。）【選択図】なし
