PRODUCT HAVING BIREFRINGENT PATTERN

摘要

PROBLEM TO BE SOLVED: To provide a product including a birefringent pattern which can form a full-color image (a latent image), having delicate color representation such as the density of each color.SOLUTION: This product includes a patterned optically anisotropic layer having two or more patterned areas different in birefringent. The areas having the same birefringent in the patterned optically anisotropic layer are formed of a plurality of drawing units. The product includes at least intensity gradation pixels approximately uniform in birefringence and an area gradation type pixel including two or more kinds of drawing units different in birefringence.
