Abstract: Stock developer solutions for photoresists contain an organic base free from metal ions and at least one compound having a specified weight average molecular weight that is selected from among polyethylene oxide compounds, polypropylene oxide compounds and ethylene oxide/propylene oxide adducts. The stock developer solutions may be diluted to requisite concentrations to prepare developer solutions for photoresists. By adding one or more of the specified compounds to the organic base free from metal ions, one can produce highly compatible stock developer solutions for photoresists that are concentrated, that have high stability in quality and that permit ease in handling and quality control. The stock developer solutions may be diluted to prepare developer solutions that are small in the tendency to foam and effective in defoaming, that assure uniform wetting and that are capable of forming resist patterns faithful to mask patterns.

Abstract: The carrier is provided with retention openings formed by two kinds of radial flanges of special shapes. The carriers are preferably made of cardboard or pasteboard diecast blanks which are introduced over the top of the containers and which by and adhesion form the carriers. The invention has application in the support and transport of containers in groups of one or more rows, especially soft drink cans or pots.
