The present invention relates to a laminate that includes a pair of substrates; and one or more photochromic films and one or more infrared (IR) shield films that are provided between the pair of substrates, wherein the photochromic films or the infrared (IR) shield films that are in contact with a pair of substrates are adhered to the substrates by an adhesion film. The laminate according to the present invention has a high durable photochromic function having a UV shielding effect and an infrared (IR) shielding effect.

Laminate having photochromic function and infrared shield function

A high adhesive acrylate monomer has a specific chemistry figure. This monomer may be easily prepared in a simplified way, and various linkers may be used between L-DOPA and an acrylate group attached to a tail of L-DOPA, so molecular weight and size of the entire material may be easily controlled. Also, various kinds of acrylate to be combined to a isocyanate compound used as a linker may be selected, so various molecules may be easily composed.
