Konica Minolta has accumulation of technologies to generate coating layers at a uniform precision in nano-order developed in manufacturing of silver halide films. Owing to know-how of these technologies, it is possible to give characteristics according to a use such as photo-sensitivity, heat-sensitivity or ink absorption to the surface of materials including various types of film sheets, glass plate or metal. The technology to coat a uniformly thin layer containing functional fine-grains or functional materials at a high rate is playing an active part in manufacturing of consumer goods and production goods in various fields, including manufacturing of functional films.
To improve productivity, it is necessary to coat plural layers (10 or more layers) simultaneously at a high rate, without coating one layer at a time. To realize such high rate and stable production, various peripheral technologies are combined such as technologies for optimization of physical properties of solutions and for simulation of hydrodynamics, a technology for designing a coating apparatus for realizing uniformity in coating width direction and rectified flow (uniform flow), the technology to make a precision coating apparatus that requires micron-order finish, high speed and uniform drying technology and the technology of automatic coating failure detection of a nondestructive type.
