Patent Name Adhesive for Printing Inks Patent Patent Owner Sanyo Chemical Industries, Ltd. Principal Applicant Address Kyoto, Japan Inventor Inagi Kosaka Application (Patent) No. 200410043332.4 Date of Application 2004.05.14 Approval Date Approval Notice No. 1696217 Auditing Notice Date 2005.11 .16 Specification CD-ROM D0546 Main Classification No. C09D11/10 Classification No. C09D11/10 Classification Original Application No. Priority Citation abstract A printing ink binder is a polyurethane resin (A) that does not contain free isocyanate groups. The polyurethane resin (A) consists of a macromolecular diol (a), an alicyclic diisocyanate (b), an alicyclic diamine (c), and a monoamine (d); and in (d) it is The number of moles of (d) containing 10 mol% or more of the secondary monoamine (d1); [(c) moles]/[(d) moles] is 5 or more and 15 or less; (A) total amines It is 0.2 or more and 20 or less; when the film (A) is made into a film, 100% stress is 0.3-2 MPa, and 300% stress is 0.3-2 MPa. According to the present invention, it is possible to provide a binder for printing ink which is not only easy to produce, but also has excellent resistance to binding and heat, and also has better adhesion to cellophane tape and higher laminating strength than conventional products. Sovereign Items 1. A binder for printing inks, which is a polyurethane resin (A) containing no free isocyanate groups, characterized in that the polyurethane resin (A) comprises a polymer diol (a), an alicyclic diisocyanate. (b) alicyclic diamine (c) and monoamine (d) composition; and in (d) containing more than 10 mole % of monoamine (d1) relative to (d) moles; [ (c) mole number]/[(d) mole number] is 5 or more and 15 or less; the total amine value of (A) is 0.2 or more and 20 or less; and the 100% stress when (A) is made into a film is 0.3 to 2MPa, 300% stress is 0.3-2 MPa.
