PURPOSE:To obtain an urethane foam, having attractant action as a feed and effective fish gathering action by phototaxic stimulation, by blending a luminous material with a specific amount of animal oil and expanding the resultant blend. CONSTITUTION:100pts.wt. polyol component in a raw material for an expansion raw material for a polyurethane is blended with (A) 5-50pts.wt. luminous material, e.g. zinc sulfide, eosine, etc., and (B) 5-50pts.wt. animal oil, e.g. tuna oil, etc. and the resultant blend is expanded by a specific method. |
