Title: A process for improving the dyeing properties of polyvinyl alcohol fibres
Inventor: OSUGI TETSURO
IPC: D06M13/12
Filed: 1953-04-08
Abstract: The dyeing properties of polyvinyl alcohol fibres are improved by treating a polyvinyl alcohol fibre which shrinks in water of 80 DEG C. not more than 5 per cent of its length, with a solution containing 0.5 to 15 per cent of formaldehyde or acetaldehyde or compounds decomposable to these in the presence of acids, an inorganic acid, and not more than 5 per cent by weight of an alkali-metal or ammonium salt of an inorganic acid.  The preferred proportions of acid are 0.5 to 25 per cent.  Polyvinyl alcohol includes copolymers of vinyl alcohol with ethylene, maleic anhydride, and acrylonitrile, providing they contain at least 80 per cent vinyl alcohol.  Specified compounds giving rise to formaldehyde or acetaldehyde are paraformaldehyde, polyoxymethylene, hexamethylenetetramine, and paraldehyde.  The polyvinyl alcohol may be pretreated by spinning an aqueous solution thereof into a coagulating bath containing an above-specified inorganic salt, removing from the obtained filaments sufficient inorganic salt to leave not more than 10 per cent and heating the filaments to 140 DEG  to 220 DEG  C. so as to raise their softening point in water to at least 80 DEG  C.  The polyvinyl alcohol fibre may be treated first with an aliphatic compound having a reactive aldehyde group so as to acetalize not more than 20 per cent of the hydroxyl groups of the polyvinyl alcohol.

Title: Methods of using capsules
IPC: B01J13/02
Filed: 1966-03-04
Abstract: 1,128,513. Capsules. KEUFFEL & ESSER CO. 4 March, 1966 [5 March, 1965], No. 9699/66. Heading B8C. Radiation-sensitive material is included in either the core or the shell of a capsule so that the shell may be disintegrated by means of electromagnetic radiation when the core material is required for use, e.g. for photographic processes such as sensitizing, developing, fixing or stabilizing photographic materials. On absorption of suitable radiation the radiationsensitive material may generate either a gas which produces -sufficient pressure to burst the shell, or heat which melts the shell. If the radiation-sensitive material is included within the core, the walls of the shell must be transparent to the disintegrating radiation. Examples of materials which generate gas on absorption of electromagnetic radiation are aromatic diazonium compounds, aromatic azido compounds and quinone-diazides, all of which produce nitrogen, and ferric salts of an organic dicarboxylic acid such as ferric oxalate and ferric ammonium oxalate, which produce carbon dioxide. Infra-red absorbers which generate heat capable of destroying the capsule shell include carbon black and synthetic absorbers such as manganese complexes of azo compounds. Examples are given in which capsules are formed by deposition of the shell material around dispersed entities of the core material, from a coacervate solution of the former. Coacervation may be induced by the addition of suitable agents, such as petroleum ether.
