摘要:
An optical product having a thin film on the surface which is obtained by subjecting a mixed gas of oxygen and a hydrocarbon compound having a double bond to plasma polymerization in the presence of an optical product, thereby forming on the surface of the optical product a thin film of a reaction product of said plasma polymerization. Said optical product having a thin film on the surface has excellent resistance to fogging due to adhesion of water drops when used in gas phase, excellent resistance to adhesion of air bubbles when used in liquid phase, high resistance to being stained by oils and fats and an excellent removability of stains due to oils and fats.

A novel polymeric thin film having a high density, high hardness and high toughness is prepared on the surface of a substrate by plasma polymerization. The gas used to provide the plasma contains a halogenated alkane and/or an alkane and optionally hydrogen and/or a halogen, the atomic ratio of halogen/hydrogen in the gas being from 0.1:1 to 5:1 and the electron temperature of the plasma in the reaction zone being 6,000K or higher and lower than 30,000K. The polymeric thin film obtained is useful on various articles for the purpose of protection, surface hardening, rust-proofing, scratch-proofing, providing a gas barrier, etc. In particular, it is suitable as the protective film for magnetic recording media. %

摘要:
In a method of basting in the tailoring of clothes wherein an adhesive is used to secure the cloth, the improvement wherein said adhesive comprises as the main component a liquid, addition-reaction-type silicone polymer. Said basting method is applicable to basting interlinings and or shoulder pads to front bodices, basting two back bodices and the like to simplify and automatize the tailoring process.
