    摘要: The inventive method for forming a cured film on a substrate surface comprises coating the surface with a room temperature curable organosiloxazane polymer comprising, in a molecule, (a) at least one organosiloxane unit represented by the unit formula (a) at least one organosiloxane unit represented by the unit formulaR.sup.1.sub.a SiO.sub.(4-a)/2,and (b) at least one organosilazane unit represented by the unit formulaR.sup.2.sub.b Si(NR.sup.3).sub.(4-b)/2,in which R.sup.1, R.sup.2 and R.sup.3 are each a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, not all of them being simultaneously hydrogen atoms, and the subscripts a and b are each a positive integer of 1, 2 or 3 with the proviso that a and b cannot be simultaneously equal to 3, in a molecule and subjecting the coating film to exposure to a moisture-containing atmosphere. The method is useful for forming a surface-protecting film or for imparting surface releasability.

    摘要: The radiation-curable organopolysiloxane composition of the invention is quite free from the problem of the migration of silicone toward the surface of a body in contact with the surface of the cured film of the composition even by curing with an extremely small dose of radiation, e.g. ultraviolet light and electron beams, for curing. The mechanism for curing is in principle the radiation-induced addition reaction between the aliphatically unsaturated bonds in a first organopolysiloxane and the mercapto groups in a second organopolysiloxane but the aliphatically unsaturated bond in the first organopolysiloxane is bonded preferably remotely from the silicon atom with an electron-attractive atom or group intervening therebetween such as the divalent groups of the formula --O--CH.sub.2).sub.2 S-- and --CH.sub.2 --O--CH.sub.2 --S--.
