COLORED RESIN COMPOSITION FOR TRANSFUSION BAG

摘要

PURPOSE: To obtain a colored resin compsn. for a transfusion bag which absorbs ultraviolet rays, improving the stability of a transfusion fluid, and does not allow a colorant contained in itself to be dissolved out into the fluid by compounding a thermoplastic resin with a pigments comprising Color Index Pigment Yellow 95 and/or 147. CONSTITUTION: This compsn. is prepd. by compounding 100 pts.wt. thermopolastic resin for a transfusion bag (e.g. polyethylene, EVA, or a soft plasticized polyvinyl chloride) with 0.02-3 pts.wt. pigment comprising Color Index Pigment Yellow 95 and/or Color Index Pigment Yellow 147. An inflation film produced from the compsn. does not allow the colorant to be dissolved out into a transfusion fluid. is transparent, and is excellent in light resistance and absorption of ultraviolet rays of 200-450nm, preventing the decomposition esp. of a transfusion fluid contg. an amino acid, etc., by the light of a fluorescent lamp.
