Abstract

This invention relates to a positive photosensitive layer composition which following a process of inversion is capable of also acting as a negative, comprising a diazo resin based on orthoquinone diazide 4-and/or 5-sulphonate and a polymer compound based on resin derived from phenol and/or a phenol derivative condensate with formaldehyde or a phenol vinyl and/or a vinyl phenol derivative polymerised by radical means in which the said composition also comprises an antioxidant comprising a phenol or polyphenol derivative having a molecular weight of more than 108.
