摘要:
A printer has a thermal head and a cooperable platen roll, which are moveable relatively apart to provide a gap. The cartridge is supplied with a removable installation device which has a guide which can swing outwardly to align the ink ribbon with the gap. When the cartridge is loaded onto locator pins on the printer, the ink ribbon is guided into the gap.

There is disclosed a printer having a thermal print head and a cooperable platen roll. The platen roll is driven to advance a web of record medium and an ink ribbon into cooperation with the print head. The printer can use an ink ribbon cartridge. The printer has a compact arrangement for the record medium supply roll, the ink ribbon cartridge, the printing mechanism, the drive mechanism, the keyboard, and the cutting mechanism for cutting tags from the web. The ink ribbon cartridge has movable guides which are aligned by spindles on the printer.

The printer has a compact arrangement for the record medium supply roll, the ink ribbon cartridge, the printing mechanism, the drive mechanism, the keyboard, and the cutting mechanism for cutting tags from the web. The supply roll is mounted on a reel having first and second side plates on a hub. A first hub member is connected to the first side plate. A second hub member is adapted to be connected either to the second side plate in opposition to the first hub member in its first position so that the first and second hub members support the supply roll or to the first hub member when the first hub member is in its second position so that the hub is adapted to support a supply roll between the first and second side plates.

A quinone diazide of formula (I) or formula (II):(S)l--(L.sup.1)m=-(Q).sub.n (I)--(L.sup.2 (-S))o-(L.sup.3 (--Q))p- (II)wherein S is a light absorbing portion having an absorption coefficient of greater than 1000 in wavelengths longer than 360 nm; Q is a quinone diazide residue; L.sup.1, L.sup.2 and L.sup.3 are connecting groups connecting S and Q, provided, however, that L.sup.1, L.sup.2 and L.sup.3 do not conjugate S and Q; l, m, n, o and p are integers; andwherein the emission intensity of the compound of formulas (I) and (II) is smaller than the emission intensity of the chromophoric group alone. Also disclosed is a light sensitive composition comprising an alkali soluble resin and the above quinone diazide compound. The quinone diazide compound of the present invention have spectral sensitization with respect to visible light and are useful in visible light projection plates and as visible laser sensing materials.
摘要:
The present invention relates to a light-sensitive composition comprising (a) a photo-crosslinkable polymer having a maleimido group at a side chain and (b) a sensitizer such as the following compounds: ##STR1## The present invention provides a light-sensitive composition having very high sensitivity; providing excellent images during only a short exposure time; and being sensitive to light of long wave length.
摘要:
A light-sensitive composition containing a polymerizable compound having at least one ethylenically unsaturated group, and a photopolymerization initiator of general formula (I): ##STR1## wherein Y represents --COOR.sub.1, ##STR2## --R.sub.3 --COOR.sub.1, --R.sub.3 --CONHR.sub.1 or --NHCO--R.sub.4 (wherein R.sub.1 represents a hydrogen atom, an alkyl group, or an aryl group; R.sub.2 represents a hydrogen atom or a methyl group; R.sub.3 represents an alkylene group; R.sub.4 represents an alkyl group, an alkoxy group, an aryl group; and l and m respectively represents integers of 1 to 10.); Ar represents a phenylene, naphthylene or heterocyclic aromatic group; X represents a chlorine atom or a bromine atom; and n represents 1 or 2.The light-sensitive composition has a good stability over time since crystallization of the photopolymerization initiator on the surface of the light-sensitive layer is inhibited.
