This invention relates to a cigarette pack transfer coating applicable to OPP film and its preparation method, belonging to the technical field of transfer coatings. The cigarette pack transfer coating comprises the following components by weight: 5-12 parts cellulose acetate propionate resin, 10-20 parts thermosetting acrylic resin, 4-10 parts thermoplastic acrylic resin, 0.06-0.2 parts leveling agent, 0.02-0.1 parts defoamer, and 75-80 parts solvent. This invention achieves high-efficiency transfer at low temperatures of 90-110℃ by employing a synergistic system of cellulose acetate propionate resin and thermosetting acrylic resin, combined with thermoplastic acrylic resin and a specific ratio of leveling agent, defoamer, and solvent. Simultaneously, it exhibits excellent gloss and flexibility properties. Compared with traditional PET transfer coatings, it reduces material costs, energy consumption, and VOC emissions, thus better meeting environmental protection requirements.

The application discloses a kind of mask pastes, the mask pastes is made of the following raw materials: resin, organic solvent, inorganic filler, pigment;The resin includes resin A1, resin A2, resin B1 and resin B2, wherein the resin A1 has first hydrophilic group, the resin A2 has first lipophilic group, the number N1 of first hydrophilic group is 200-2000, the number M1 of first lipophilic group is 200-2000;The resin B1 has second hydrophilic group, the resin B2 has second lipophilic group, the number N2 of second hydrophilic group is 50-5000, the number M2 of second lipophilic group is 150-500.The resin component in the mask paste of the application is improved, different kinds of hydrophilic modified resin and lipophilic modified resin are matched with each other, which can not only meet the excellent water washing performance of the paste, but also meet the good printing resolution of the paste, and the application range is wider.
