Abstract: PURPOSE:To obtain a photoreactive formed substance capable of forming a high density clear image shielding ultraviolet rays and visible rays by using a pbotoreactive composition consisting of colloidal carbon and a pbotodegradable or photocrosslinkable substance. CONSTITUTION:To a substance inducing photodegradation or pbotocrosslinking reaction with activated rays, e.g. Sun Wipe-on of Koyo Kagaku KK or FPPR of Fuji Yakuhin Kogyo KK is added about 3-60, preferably 6-40wt% of colloidal carbon particles such as gas black or naphthalene black particles having an average aggregated particle size of 1mu or less and an average primary particle size of about 0.1mu or less. An organic solvent is further added to disperse them. The resulting carbon-dispersed polymer solution is coated onto a substrate such as a polymer film, a glass sheet or paper to form a photoreactive composition film of about 1- 15mu.

Abstract: PURPOSE:To increase active capacity and enable the easy regeneration use by compounding catalyst fine particles in fibrils and connecting the catalyst surfaces to the outside of the fibrils by fine cavities. CONSTITUTION:Polymer solution containing catalyst fine particles is made into fine fiber-form or film-form by suitable methods such as emulsion flash spinning method, flash spinning method, solution shearing method. With the fine fiber-form or film-form catalyst thus made, the active surfaces of the catalyst particles dispersed in the inside or the catalyst fine particles dispersed in partially exposing their surfaces are connected to the outside of the fine fiber-form material or film-form material by fine cavities and their specific surface area is set at 3m /g or more. The abovementioned catalyst may be sheeted, if desired, alone or with other pulp-form material and may be used as sheet-form material.
