    摘要: A method for transferring patterns on a silicone ladder type resin, which comprises: applying onto a substrate a silicone ladder type resin to be represented by the following general formula (I) ##STR1## (where: R.sub.1 denotes a phenyl group or a lower alkyl group, and two R.sub.1 's may be the same or different kinds; R.sub.2 denotes hydrogen atom or a lower alkyl group, and four R.sub.2 's may be the same or different kinds; and n represents an integer of from 5 to 1,000); drying the thus applied resin layer; thereafter applying onto the resin layer a cresol novolac type positive photo-resist; forming a predetermined pattern in the photo-resist layer; subjecting the photo-resist layer to pretreatment; and finally etching the silicone ladder type resin.An etching liquid for etching a silicone ladder type resin, which comprises an aromatic type solvent.

    摘要: A material for spacecrafts pertaining to this invention is made of a compound containing the group IV b elements, as a material of which proof for oxygen atom is absolutely necessary. The application of this material, in the form of a shield part (a resin layer) for covering at least a portion of material used in a structural part of the spacecraft enables a long use (from several months to several decades or more) in the oxygen atom environment in the space, which was impossible in the part.
