Examples
manufacture example 1
[0071] 884 parts of polypropylene glycol with a number-average molecular weight of 2,000 (manufactured by ADEKA Co., Ltd., trade name "Adeka Polyester P-2000") (hereinafter referred to as PPG2000), 884 parts of isopropyl After 106 parts of phorone diisocyanate (hereinafter referred to as IPDI), 250 parts of n-lauryl acrylate (hereinafter referred to as LA), and 0.4 part of stannous octoate, the temperature was raised to 80° C. and kept for 3 hours to obtain an intermediate isocyanate group LA solution of end-capped urethane prepolymer. Next, 10 parts of 4-hydroxybutyl acrylate (hereinafter referred to as 4HBA) was added, the temperature was kept at 80° C. for 2 hours, and the completion of the reaction was confirmed by NCO measurement, thereby obtaining a polyurethane having a weight average molecular weight of 52,000 and an average number of acryloyl groups of 2 LA solution of acrylate (A-1) (hereinafter referred to as (A-1) component).
manufacture example 2
[0073] 868 parts of PPG2000, 122 parts of dicyclohexylmethane diisocyanate (hereinafter referred to as hydrogenated MDI), 250 parts of 2-ethylhexyl acrylate (hereinafter referred to as 2-EHA), and octanoic acid were added to the same reaction apparatus as in Production Example 1. After adding 0.5 part of stannous, the temperature was raised to 80° C. and the temperature was maintained for 3 hours to obtain a 2-EHA solution of an isocyanate group-terminated urethane prepolymer as an intermediate. Next, 10 parts of 4HBA was added, the temperature was kept at 80° C. for 2 hours, and the completion of the reaction was confirmed by NCO measurement, thereby obtaining a urethane acrylate (A-2) (hereinafter referred to as a weight average molecular weight of 56,000 and an average number of acryloyl groups of 2) (A-2) component) 2-EHA solution.
manufacture example 3
[0075] 856 parts of PPG2000, 119 parts of IPDI and 0.5 part of stannous octoate were added to the same reaction apparatus as in Production Example 1, the temperature was raised to 80° C. and the temperature was kept for 3 hours to obtain an isocyanate group-terminated urethane prepolymer as an intermediate thing. Next, 25 parts of 2-hydroxyethyl acrylate (hereinafter referred to as HEA) was added, the temperature was kept at 80° C. for 2 hours, and the completion of the reaction was confirmed by NCO measurement, thereby obtaining a polyurethane having a weight average molecular weight of 25,000 and an average number of acryloyl groups of 2 Acrylate (A-3) (hereinafter referred to as (A-3) component).
