    摘要: A photosensitive borosilicate glass which consists essentially in calculated weight percent on an oxide basis of 20-80% SiO.sub.2, 8-40% B.sub.2 O.sub.3, 0-6% Li.sub.2, 0-28% Na.sub.2, 0-25% K.sub.2 O, the total Na.sub.2 O+K.sub.2 O being 10-28%, 0-18% Al.sub.2 O.sub.3 and minor amounts of photosensitizing agents silver, cerium oxide, antimony oxide and bromine and/or chlorine, the cation ratio of R.sub.2 O--Al.sub.2 O.sub.3 to B.sub.2 O.sub.3 being at least 0.6.
