HEAT SEALING AGENT, LAMINATE BODY USING SAME, AND SOLAR CELL MODULE

WIPO Patent Application WO/2013/136861

A1

The purpose of the present invention is to provide a heat sealing agent with excellent adhesiveness to any substrate and capable of forming a heat seal layer having wet heat resistance of a level that does not result in decreased adhesiveness due to the influence of heat and water. This invention relates to a heat sealing agent which contains a urethane resin (A), a polyolefin resin (B), a crosslinking agent (C) and an aqueous medium (D). The urethane resin (A) is obtained by reacting a urethane resin having an isocyanate group, with at least one item selected from a group consisting of compounds having a primary amino group, compounds having a hydrazide group, and hydrazines. The crosslinking agent (C) contains an alkylated methylol melamine resin (c1) and an epoxy compound (c2), and either or both of the urethane resin (A) and the polyolefin resin (B) has a functional group which reacts with epoxy groups.
