Abstract
A protective film includes a protective layer, an adhesive layer, and a releasing layer. The protective layer, the adhesive layer, and the releasing layer are stacked together in that order. The adhesive layer includes a pressure-sensitive adhesive in an amount by weight of about 90 parts to about 100 parts, inorganic fluorescent powders in an amount by weight of about 0.05 parts to about 0.5 parts, and a curing agent in an amount by weight of about 0.5 parts to about 3 parts.
Claims16
A protective film comprising:
- a protective layer;
- an adhesive layer;
- and
- a releasing layer, the protective layer, the adhesive layer, and the releasing layer stacked together in that order;
- wherein the adhesive layer comprises a pressure-sensitive adhesive in an amount by weight of about 90 parts to about 100 parts, inorganic fluorescent powders in an amount by weight of about 0.05 parts to about 0.5 parts, and a curing agent in an amount by weight of about 0.5 parts to about 3 parts.
A method for making a protective film comprising:
- mixing a pressure-sensitive adhesive in an amount by weight of about 90 parts to about 100 parts and inorganic fluorescent powders in an amount by weight of about 0.05 parts to about 0.5 parts, and adding a curing agent in an amount by weight of about 0.5 parts to about 3 parts in the mixed pressure-sensitive adhesive and inorganic fluorescent powders to form a mixture;
- providing a protective layer, and coating the mixture on the protective layer;
- heating the protective layer with the mixture coated thereon, thus causing the pressure-sensitive adhesive and the curing agent in the mixture to undergo a solidification reaction to form an adhesive layer on the protective layer;
- and
- covering a releasing layer on a surface of the adhesive layer facing away from the protective layer, thereby forming the protective film.
