Document Type and Number:
Japanese Patent JP3160578
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an adhesive having both excellent oxygen-blocking properties and moisture-preventing properties.
SOLUTION: This method for laminating a first film of a polymer material to a second film of the polymer material comprises a step for forming (I) an adhesive mixture by mixing (A) a hydroxyl-terminal polyester without a solvent, composed out of one kind of a linear aliphatic diol and one kind of linear dicarboxylic acid, with (B) one kind of diisocyanate, or forming (II) an adhesive mixture by forming (C) an urethane prepolymer by reacting the whole or a part of the isocyanate B with a part of the polyester A and mixing the remainder of the polyester A with the remainder of the diisocyanate B and the urethane polymer C, a step for sticking the first and the second films by the adhesive mixture (I) or (II), and a step for completely reacting the diisocyanate B with the polyester A.
