Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a synthesized resin for a printing ink which is excellent in the wear resistance of a printing plate, the covering power of a printed material and the adhesiveness. SOLUTION: This resin comprises a solvent-soluble polyurethane polyurea of formula I with a number average molecular weight of 20,000-100,000 having a 100% stress and an elongation, in a shape of a film, of 1-20 kgf/cm and 200-2,000% respectively. Formula I: B-[X-(A-X)m -Y]n -X(A-X)m -B [wherein B is a polymerization terminator portion comprising a monoamine having two hydroxy groups of a primary hydroxy group and a secondary hydroxy group shown in Formula II: (wherein p is an integer of 1-6), X is an aliphatic diisocyanate portion and/or an alicyclic diisocyanate portion, A is a polyester polyol portion having a number average molecular weight of 500-5,000, Y is an aliphatic diamine portion and/or an alicyclic diamine portion, and m is an integer of 1-10, and n is an integer of 3-35].
