aus Lithographiestein.made of lithographic stone.
Um lichtempfindliche Schichten auf Unterlagen, insbesondere auf Lithographiesteinen zu befestigen, hat man schon Zwischenschichten aus pulverförmigen, in Breiform aufgetragenen Substanzen angegeben, aber es hat sich herausgestellt, daß diese praktisch nicht brauchbar sind, da sie sich nicht dünn und gleichmäßig genug aufstreichen lassen. Nach der vorliegenden Erfindung sollenAround light-sensitive layers on substrates, especially on lithographic stones To attach, you already have intermediate layers of powdery, porridge form applied substances, but it has been found to be practical are not usable because they cannot be spread thinly and evenly enough. According to the present invention
ίο' deshalb zu dem gleichen Zweck Harzlösungen verwendet werden, die sich dünn genug aufstreichen lassen und dann eine feste Verbindung der lichtempfindlichen Schicht mit. der Unterlage bewirken, ähnlich wie man sie zum Festkleben unentwickelter, aber belichteter Leimhochdruckschichten auf Zink bereits angegeben hat, während sie bei Papier als Unterlage in etwas dickerer Schicht gerade das leichte Abziehen von lichtempfindlichen Schichten ermöglichen.ίο 'therefore resin solutions for the same purpose that can be spread thin enough and then a firm connection the photosensitive layer with. the backing effect, similar to how you would use it for Bonding of undeveloped, but exposed, high-pressure glue layers on zinc already indicated has, while with paper as a base in a slightly thicker layer just the easy peeling off of light-sensitive Enable shifts.
Man kann die käuflichen Lacke verwenden oder sich durch Auflösen eines Harzes in einem für zweckmäßig befundenen Lösungsmittel selbst eine solche Mischung herstellen. Zweckmäßig ist es jedoch, das Harz möglichst fettfrei zu verwenden.You can use the commercially available varnishes or dissolve a resin in produce such a mixture yourself using a solvent found to be suitable. However, it is useful to use the resin as fat-free as possible.
Das betreffende Mittel wird dünn aufgestrichen und trocknen gelassen. Wenn dies geschehen ist, bringt man die lichtempfindliche Schicht direkt auf, oder man beginnt erst mit einer der sonst üblichen Zwischenschichten und läßt erst dann die lichtempfindliche Schicht folgen.The agent in question is spread thinly and allowed to dry. If this is done, you apply the photosensitive layer directly, or you start only with one of the otherwise usual intermediate layers and only then leaves the light-sensitive one Follow shift.
