Title:
METHOD FOR ENVIRONMENTALLY-FRIENDLY LONG-LASTING THERMAL PAPER
Document Type and Number:
WIPO Patent Application WO/2024/066328
Kind Code:
A1
Abstract:
Environmentally-friendly long-lasting thermal paper, comprising a base material layer (1), a ground color layer (2), a thermally sensitive covering layer (3), and a protective layer (4) that are arranged in sequence from bottom to top. The thermally sensitive covering layer (3) is obtained by coating the ground color layer (2) with a thermally sensitive covering layer raw material and then drying same, and the thermally sensitive covering layer raw material is an emulsion formed by mixing acrylic hollow microspheres with a host resin. Acrylic hollow microspheres capable of changing from a non-transparent state to a transparent state after being heated and broken are used as a thermally sensitive covering layer to cover a ground color layer, so as to obtain thermal paper having thermal color rendering properties.
