摘要： PURPOSE:To manufacture the title plate with high reproducibility and a low inferiority rate without causing enviromental pollution due to waste solvent by forming a photosensitive resin into the shape of the desired printing plate and applying active rays of light to set the plate. CONSTITUTION:A metal plate such as a zinc plate, a PS zinc plate or a copper plate or a resin plate such as a nylon plate is used in letterpress, and a thermosetting resin such as phenol resin is hot pressed under predetermined conditions to obtain a female mold. Using this mold a photosensitive resin is formed into the shape of a desired printing plate by casting in case of a liquid resin or press or injection molding in case of a solide resin. A burr forced out of the mold or a resin plate resulted in a failure can be recycled. The formed resin plate is then irradiated with active rays of light from a chemical lamp, a high voltage mercury lamp, a xenon lamp or the like to set the exposed portion, and by releasing from the mold a printing resin plate is obtained having a relief which closely follows the negative.

摘要： PURPOSE:To enhance the dispersibility, wear resistance, etc. by using polyurethane resin having tertiary amino groups and a polyisocyanate compound as components of a binder for the magnetic layer. CONSTITUTION:A magnetic layer for magnetic recording is formed using a binder consisting of thermoplastic polyurethane resin having 10,000-50,000mol. wt. and tertiary amino groups represented by the formula in the molecular chain and low mol.wt. polyisocyanate having 150-7,000mol.wt. and >=2 isocyanate groups or further contg. other resin. The amount of the polyisocyanate is 3- 40pts.wt. per 100pts.wt. polyurethane resin.
