The present invention relates to a method of producing an optical fiber-processing phase mask having minimized connection errors that may degrade the spectral line shape and group delay characteristics of an optical fiber diffraction grating fabricated by using the phase mask. The present invention provides a method of producing an optical fiber-processing phase mask having a repeating pattern of grating-shaped grooves and strips provided on one surface of a transparent substrate, so that diffracted light produced by the repeating pattern is applied to an optical fiber to fabricate a diffraction grating in the optical fiber by interference fringes of diffracted light of different orders. In making a mask having a plurality of juxtaposed patterns (P1 to P5) having a linearly or nonlinearly increasing or decreasing pitch and a uniform groove-strip width ratio, multiple exposure is carried out to minimize difference between the pitch at the joint between patterns having different pitch data and the pitch in each individual pattern.

The present invention relates to a thermosensitive lithographic printing original plate comprising a substrate, a hydrophilic layer containing a hydrophilic binder polymer, and a microcapsuled oleophilic material which forms an image area by heating; the hydrophilic binder polymer having a three-dimensional cross-link and a functional group which chemically combines with the oleophilic material in the microcapsule when the microcapsule is decomposed, and the microcapsuled oleophilic material having a functional group which chemically combines with the hydrophilic binder polymer when the microcapsule is decomposed.The thermosensitive lithographic printing original plate of the present invention is excellent in printing durability and storage property and provides prints having clear images because the plate does not collect scumming. Further, development is not required in the platemaking process so that there are no problems with waste treatment and the like. Consequently, the original plate can be practically applied not only to a light printing such as a printing in offices but also to a rotary press of newspaper, form printing and the like.
