Photosensitive element
View Patent ↗A photosensitive element 1 comprising a support film 10 and a layer (photosensitive layer) 20 composed of a photosensitive resin composition formed on the support film 10 , wherein the haze of the support film 10 is 0.01-2.0%, the total number of particles and aggregates with diameters of 5 μm or larger in the support film 10 is no greater than 5/mm 2 , the photosensitive layer 20 contains (A) a binder polymer, (B) a photopolymerizing compound with an ethylenic unsaturated bond and (C) a photopolymerization initiator, and the thickness of the photosensitive layer 20 is 3-30 μm.
1. A photosensitive element comprising a support film and a layer comprising a photosensitive resin composition formed on the support film,
wherein the haze of the support film is 0.01-2.0%, and the total number of particles with diameters of 5 μm or larger and aggregates with diameters of 5 μm or larger in the support film is no greater than 5/mm 2 measured using a polarizing microscope at a magnification sufficient to detect those particles and aggregates having diameters of 5 μm or larger,
wherein the layer comprising the photosensitive resin composition includes
(A) a binder polymer;
(B) a photopolymerizing compound with an ethylenic unsaturated bond; and
(C) a photopolymerization initiator, and wherein a thickness of the layer comprising the photosensitive resin composition is 3-30 μm.
2. A photosensitive element according to claim 1 , wherein the weight-average molecular weight of the (A) binder polymer is 30000-150000.
