Abstract: The present disclosure provides a separator for lead acid storage batteries, the separator comprising a base material and a conductive layer that is superposed on at least one surface of the base material. The conductive layer has cracks; and the conductive layer contains a fibrous conductive material which has an average fiber diameter that is from 1% to 30% of the average crack width of the cracks.

Abstract: The present invention provides: a separator for lead acid storage batteries, the separator exhibiting excellent charge acceptance performance and excellent liquid loss characteristics when in use under PSoC, while being not susceptible to the occurrence of ply separation within a lead acid storage battery and having good ER; and a lead acid storage battery which uses this separator for lead acid storage batteries. The present invention provides a separator for lead acid storage batteries, the separator comprising a base material and a conductive layer that is superposed on at least one surface of the base material.

Abstract: The present invention relates to a photosensitive alkali-soluble silicone resin composition comprising an alkali-soluble silicone resin (A) which comprises a carboxyl group or a dicarboxylic acid anhydride group in one molecule; an alkali-soluble resin (B) whose acid value is between 10 mgKOH/g and 200 mgKOH/g; and a photoinitiator (C). The (A) or (B) ingredient may comprise a photosensitive unsaturated double bond group, or the photosensitive alkali-soluble silicone resin composition may further comprise a compound (D) which comprises a photosensitive unsaturated double bond.
