    摘要： A liquid photosensitive resin composition for forming relief structures which comprises an unsaturated polyesterpolyetherpolyurethane prepolymer, an ethylenically unsaturated addition-polymerizing monomer and a photopolymerization initiator, and in which the weight ratio of at least one of the polyesterdiol segments of the prepolymer to at least one of the polyesterdiol segments thereof ranges from 1:3 to 4:1 and the polyesterdiol segments are each independently a polyesterdiol segment comprising repeating units represented by general formula (1) wherein (R 1 represents a divalent aliphatic or aromatic group) or a polyesterdiol segment comprising repeating units represented by general formula (2). A relief structure (e.g. a press plate) produced from the composition scarcely causes tunneling of the relief and has an improved durability.

    摘要： The invention is concerned with an isocyanate-reactive composition comprising a polymer having a molecular weight of at least 500 containing a plurality of groups of the formula :
    wherein R¹ represents hydrogen or a hydrocarbon radical;
    R² represents a hydrocarbon radical;
    R³ represents an organic radical carrying at least one isocyanate-reactive group, and
    R⁴ represents hydrogen or an optionally substituted hydrocarbon radical. Such compositions are useful for making moulded elastomers and flexible foams.
