To provide a coating agent capable of forming a coating layer or film excellent in moisture permeability, flexibility and tensile strength. A coating agent comprising an isocyanate group-containing prepolymer obtainable by reacting a polyol mixture (A) and a polyisocyanate compound (B), wherein the polyol mixture (A) is a mixture of at least two polyoxyalkylene polyols which are different in the number of hydroxy groups or the hydroxy value, and said mixture has an average number of hydroxy groups being from 2.2 to 2.6, a molecular weight per hydroxy group being from 1,500 to 10,000 and an oxyethylene group content being at least 60 mass %.

Coating composition

A reactive hot melt adhesive containing, as the main component, a blocked prepolymer made by reacting a linear prepolymer having isocyanate groups with a blocking agent, said blocked prepolymer having a number average molecular weight of at least 11,000 and a melt viscosity of at least 1,000 poise at a temperature of 110.degree. C.

Reactive hot melt adhesive and adhesive composite sheet material

Laminated safety glass having an at least two-layered structure comprising an inorganic glass layer and a synthetic resin layer, and having an inorganic glass surface on one side and a synthetic resin surface on the other side, characterized in that the major portion of the synthetic resin layer comprises a polyurethane type thermoplastic resin, said polyurethane type thermoplastic resin being a resin obtained from a high molecular weight diol composed of a combination of from 40 to 70% by weight of a poly(1,6-hexylene carbonate)diol and from 30 to 60% by weight of a polyester diol, a chain extender, and a non-yellowing type diisocyanate compound, as essential starting materials.
