PURPOSE: To obtain a metal plate having the excellent bonding strength at a relatively low temperature and heating in a short time by forming a painted film, which has the functional group indicating cross-linking reactivity and the main components comprising a thermoplastic resin, whose thermoplasticity revelation temperature is specified, and two kinds of heat sensitive cross-linking agents, wherein the cross-linking reactivity revelation temparature satisfies a specified requirement, on one surface of the metal plate.
CONSTITUTION: The heat-sensitive-adhesice-resin painted metal plate is formed by coating at least one surface of a metal plate with a coating film, wherein a thermoplastic resin A having 80° of the thermoplastic revelation temperature or more and heat sensitive agents B1 and B2 of two kinds having the different corss-linking- reactivity revelation temparatured are main components. Here, the cross-linking- reaction revelation temperatures TB1 and TB2 for the two kinds of heat sensitive cross-linking agents B1 and B2 are selected so as to satisfy the requirement for TB1<TB2, and the thermoplastic revelation temperature TA of the thermoplastic resin A is selected so as to satisfy the requirement for TB1<TB2. The heat-sensitive-adhesive- resin painted metal plate is obtained by painting and drying the surface coating liquid containing the component on the surface of the metal plate.
