A novel incombustible sound-absorbing electric radiation-absorbing ceiling panel having a thickness of from 1 mm to 30 mm is obtained by subjecting a water-dispersed slurry of a mixture of from 67 to 92 wt-% of a rock wool, from 0.5 to 8 wt-% of a beaten pulp, from 2 to 13 wt-% of a binder made of an organic resin, from 0.15 to 1 wt-% of a flocculating agent, from 0.5 to 10 wt-% of a natural mineral fiber and from 0.

Abstract: A method for forming a resin pattern which includes selectively polymerizing a photopolymerizable resin utilizing a light radiated from a photosensitive substance to form a desired resin pattern. A photosensitive substance layer is formed in a desired pattern on a substrate (or in a substrate when it is light permeable). The photosensitive substance absorbs an irradiation light and radiates a light of a longer wavelength than that of the irradiation light. A photopolymerizable resin layer formed on the substrate is not activated by the irradiation light but is activated by the light radiated from the photosensitive substance. The photopolymerizable resin layer is irradiated with an irradiation light capable of exciting the photosensitive substance and the photo-polymerizable resin is polymerized in the pattern of the photosensitive substance layer with the light radiated from the photosensitive substance.
