Polymerization Example 1-5
[0138] The reaction was completed in the same manner as in Polymerization Example 1-1 except that 183 parts of ethyl acetate, and 60.0 parts of n-butyl acrylate and 8.9 parts of n-butyl methacrylate as a monomer (a), 6.9 parts of N-vinylpyrrolidone as a monomer (b), 6.4 parts of isobornyl acrylate as a monomer (d), and 0.49 parts of AIBN were used. The content of non-volatile components in the resulted acrylic resin solution was regulated to 30%, to find a viscosity of 30 mPa.s. The weight-average molecular weight based on polystyrene calibration standard by GPC was approximately 84,800.
Polymerization Example 1-6
[0139] The reaction was completed in the same manner as in Polymerization Example 1-1 except that 159 parts of ethyl acetate, and 45.0 parts of n-butyl acrylate and 23.4 parts of n-butyl methacrylate as a monomer (a), 3.0 parts of N-vinylpyrrolidone as a monomer (b), 0.4 parts of acrylic acid as a monomer (c), and 0.43 parts of AIBN were used.

[0174] An acrylic resin composition, adhesive, optical laminated film and optical laminate were produced according to Example 1 using the acrylic resins (1) and (2) at weight ratios shown in Tables 1-3. Evaluation of the resulted optical laminate was conducted in the same manner as in Example 1, and the results are shown in Tables 1-3 together with that of Example 1.
