Latest Patents

Minezaki's latest patents include a groundbreaking lightsafe masking film. This invention features a transparent substrate with a transparent, lightsafe layer that is peelably provided over its surface. 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 innovative masking film is designed to be used alongside conventional yellow or amber masking films for effective masking of photosensitive materials.
