Zusammenfassung:	PROBLEM TO BE SOLVED: To supply an injection needle with which perceptible pain is more relieved than the pain received by currently commercially marketed needles. SOLUTION: This lubricated injection needle 10 includes an elongated tube having an outside surface, a base end 16, a terminal 18 and a hole 20 opened therethrough. The needle includes a tacky adhesive lubrication coating 4 applied on the outside surface of the tube 12. The lubrication coating 24 has a first layer 26 formed from an at least partially curing org. siloxane copolymer and polydimethyl siloxane having tacky adhesive power of about >=100 centistokes. The coating has a second layer 28 contg. polydimethyl siloxane which is applied on the film 26 as a secondary stage and has the tacky adhesive power from about 50 centistrokes to 350 centistrokes.
