Title: Naohiko Kiryu: Innovator in Photosensitive Materials
Introduction
Naohiko Kiryu is a prominent inventor based in Urawa, Japan. He has made significant contributions to the field of photosensitive materials, holding a total of eight patents. His innovative work has advanced the technology used in photomechanical reproduction processes.
Latest Patents
One of Kiryu's latest patents is a lightsafe masking film. This film includes a transparent substrate and a transparent, lightsafe layer that is peelably provided over the surface of the substrate. The layer contains a light yellow colorant and a blue colorant, resulting in a light green color. The spectral transmittance of this layer does not exceed 1% in the wavelength region between 350 nm and L.sub.max, where L.sub.max is 420 nm or more. However, it exceeds 1% in the wavelength region longer than L.sub.max, with a maximum spectral transmittance greater than 50% in the 500-570 nm range. This light green masking film is particularly useful when combined with conventional yellow or amber masking films for masking photosensitive materials in photomechanical reproduction processes.
