    Abstract: PURPOSE: To make it possible to obtain various excellent mechanical characteristics by using specific polyurethane which is soluble in tetrahydrofuran, has no isocyanate groups, has side chains and has urea groups (plural) contg. OH groups at chain terminals as a binder. CONSTITUTION: The polyurethane which is soluble in the tetrahydrofuran, has no isocyanate groups, has the side chains, has the urea groups contg. the OH groups at the chain terminals and has a mol. wt. of 40000 to 2000000 is used as the thermoplastic polyurethane. The polyurethane formed in such a manner that the ratio of the OH groups of components A to C: the NCO groups of a component D: the amino groups of a component E are 1:1.03 to 1.3:0.03 to 0.3 from A. 1mol mixture composed of polydiol having a mol. wt. of 400 to 4000 and A2) polydiol having a mol. wt. exceeding 1400 of >=10 in the molar ratio of A1 to A2, B. 0.3 to 10mol mixture composed of arom. diol and B2) straight chain diol, C. 0.05 to 0.5mol tri- or polyol, D. 1.3 to 13mol diisocyanate, E. 0.09 to 2mol aminoalcohol is used. As a result, the binder which is excellent in a mechanical behavior is obtd.

    Abstract: PURPOSE: To obtain a recording material capable of developing with a developing solution having various pH value by incorporating methacryl anilide or acryl anilide in a polymer binder by polymerization. CONSTITUTION: As the polymer binder, at least one kind of a polymer binder and if necessary other assistants and additives are incorporated. Methacryl anilide or acryl anilide is incorporated in the polymer binder by polymerization, And the development by a water based solution is possible by incorporating 1-60wt.% (metha)acryl anilide per total quantity of the polymer binder or carboxyl group. As a result, the development in the wide pH range is possible and then various kinds of the developers are enabled to he used without adversely affecting on regeneration quality and the hydrophilicity of non-pressed part of a printing plate body.

    Abstract: PURPOSE: To obtain an evaporation suppressing agent for plant, containing an acetylene compound and phenylbenzylurea as active components, effective for suppressing the evaporation from plant by synergistic action and capable of preventing the damage of a plant caused by heat and dry stress. CONSTITUTION: This agent contains at least one kind of acetylene compound of the formula I [R is CH2 OH, COOH, CH2 OR (R is a 1-8C alkyl, a 2-8C alkoxyalkyl, phenyl, etc.), etc.; X is OR (R is a 1-8C alkyl); Y is OR (R is R ) or X and Y together form a substituted 2-5C alkyleneoxy, etc.] and at least one kind of phenylbenzylurea of the formula II (R is H, a 1-4C alkyl or alkoxy, phenyl, etc.; R to R are each H, a 1-4C alkyl or alkoxy, a halogen, phenyl, OH, etc.) as active components. The agent is sprayed or scattered on a plant or soil or used as a treating agent for the seed of a plant.
