PURPOSE:To obtain the titled composition capable of fixing at a low temp. by incorporating to said composition, a polyester resin obtd. by copolycondensating a specific diol component, a carboxylic acid component, 5-30mol% of a specific two or more valence alcohol and/or epoxy resin contg. a tertiary amino group on the basis of the total components as a main component of a binding agent. CONSTITUTION:The main component of the binding agent comprises the polyester resin obtd. by copolymerizing the diol component shown by formula I, the carboxylic acid component composed of a tetra carboxylic acid or its acid anhydride or its lower alkyl ester shown by formula II and 5-30mol% either the two or more valence alcohol or the carboxylic acid shown by formulas III-V or the two or more valence alcohol and/or the epoxy compd. contg. the tertiary amino group shown by formula VI. The above described polyester resin has 80-180 deg.C softening point. |
