Abstract

The invention discloses a transfer adhesive composition for aluminum layer transfer printing and a preparation process, and relates to the field of adhesives, 200-500 parts of acrylic acid modified waterborne epoxy resin and OP-10 (alkylphenol polyoxyethylene ether) are subjected to primary dispersion at 10-30 DEG C, then 100-500 parts of imidazole closed waterborne polyurethane dispersion and a defoaming agent are added, and secondary dispersion is performed; and finally adding an auxiliary agent, and uniformly dispersing to obtain a finished product. According to the invention, by controlling the dispersion process and pretreating the imidazole closed type aqueous polyurethane dispersion, the phase separation is avoided for 12 months at the temperature of 40 DEG C, the stability of the adhesive is greatly improved, and the adhesive has the excellent properties of high adhesion, folding resistance and high glossiness, improves the tension resistance of a transferred pattern, and has light reflection resistance.
