发明名称 HIGH HARDNESS FILM
摘要 <p>Provided is a high hardness film which is thin and lightweight and is able to be reduced in the occurrence of curling or delamination, while maintaining high surface hardness. This high hardness film is characterized by comprising: a front surface film (20a) which has a first base (12a) and a hard coat layer (11a) that is laminated at least on the front surface of the first base (12a); a back surface film (21a) which has a second base (12b) and a hard coat layer (11b) that is laminated at least on the back surface of the second base (12b); and an adhesive layer (13) which is arranged between the back surface of the front surface film (20a) and the front surface of the back surface film (21a), and which bonds the films with each other. This high hardness film is also characterized in that: the thickness t1 of the first base (12a) and the thickness t2 of the second base (12b) have a relationship represented by t1 ≤ t2 ≤ 1.1 × t1; and the dynamic shear storage moduli G'(20°C) and G'(80°C) of the adhesive layer (13) satisfy the formulae below. 1 × 105 Pa ≤ G'(20°C) ≤ 1 × 107 Pa 1 × 104 Pa ≤ G'(80°C) ≤ 1 × 106 Pa</p>
