Title:
FINGERPRINT RESISTANCE EVALUATION METHOD, LAMINATE, PRODUCTION METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/153457
Kind Code:
A1
Abstract:
Provided are: a fingerprint resistance evaluation method that accounts for wipe-off performance and can also be applied to on-vehicle display devices; a laminate that exhibits superior fingerprint resistance satisfying an evaluation criterion when evaluated using the evaluation method; a production method therefor; and a display device having the laminate. Specifically provided is: a fingerprint resistance evaluation method for evaluating the fingerprint resistance of an object surface, said method being characterized by using the measured value differential ΔL*(θ) of a site on the object surface to which an artificial fingerprint liquid has been transferred and then wiped off once and a site on the object surface to which the artificial fingerprint liquid has not been transferred, as determined by means of a multi-angle colorimeter using formula (1) defined in the description. Also provided are a laminate having a surface that exhibits a ΔL*(θ) of 0.1 or less, a production method therefor, and a display device having the laminate.
