Title:
LASER-PRINTED DISPLAY BODY AND PACKAGING
Document Type and Number:
WIPO Patent Application WO/2022/080211
Kind Code:
A1
Abstract:
[Problem] To provide, with high productivity, a high-quality display body that has particularly high concealing properties among laser-printed display bodies, for which print peeling does not occur even when an external stimulation such as rubbing is applied, and for which characters are clearly visible due to the high density and definition of the printing. [Solution] This display body is characterized by: including at least one layer of a white print layer on which printing by laser irradiation is possible, the white print layer including a print section that is printed on by a laser and a non-print section; and satisfying the following (1) to (3). (1) An absolute value of a difference in color L* values between the print section and the non-print section is 1.0-10.0; (2) a total light transmittance of the non-print section is 8-50%; and (3) a thickness reduction rate of the print section in a cross-section direction is 1-80% by volume with respect to the non-print section.
