摘要:
Disclosed is a thermosensitive recording material comprising a sheet-shaped support and a thermosensitive recording layer which is formed on at least one surface of the support and comprises a colorless or light-colored dye precursor and a color developer capable of reacting with the dye precursor and inducing color formation therein upon application of heat thereto, the color developer comprising a compound represented by the following formula (I) or analog thereof:: The thermosensitive recording material has high sensitivity and can prevent white background portions from coloring and recorded images from decolorizing in an environmental resistance test.
摘要:
A thermosensitive reversible color-developing and disappearing agent includes an aromatic compound having at least one group of the formula, -SO₂NHCXNH-, wherein X = O or S atom, and at least one straight chain alkyl group with 11 or more carbon atoms, and is reactive with a dye precursor in a thermosensitive recording material to thereby record colored images on the recording material upon heating imagewise, and make the colored images disappear upon heating to a temperature lower than the colored image-forming temperature.
摘要:
A thermosensitive recording material having a high whiteness and capable of forming clear colored images with an excellent resistance to oil and plasticizers is provided with a thermosensitive colored image-forming layer formed on a substrate sheet and comprising a substantially colorless dye precursor, a binder and a color-developing agent comprising at least one aromatic compound having, per molecule thereof, at least two functional sulfonylaminocarbonyl-amino groups of the formula (I): wherein X is an oxygen or sulfur atom.
摘要:
Compounds of the formula (I) : or a pharmaceutically acceptable salt are described wherein R' is hydrogen or methyl, R 2 is C 1-4 alkyl, substituted by one or two groups selected from hydroxy, C 1-4 alkoxy, carbamoyl, C 1-4 alkoxycarbonyl and trifluoromethyl, provided that the carbon atom adjacent to the nitrogen atom is not substituted by hydroxy and that no carbon atom is disubstituted by hydroxy, or -A-R 4 where A is C 1-4 alkylene - (straight or branched) and R' is optionally substituted aryl or heteroaryl, R 3 is cyano, -COR 5 or - SO 2 R 6 where R 5 is C 1-4 alkoxy or optionally substituted phenyl and R 6 is NHR 7 , C 1-4 alkyl or optionally substituted aryl; and R 7 is hydrogen or C 1-4 alkyl, R 2 can also be C 3-6 cycloalkyl, allyl or propargyl when R 3 is cyano, and R 2 can also be hydrogen or C,. 4 alkyl when R 3 is -COR 5 or -SO 2 R 6 . These compounds have inotropic, vasodilator, broncho-dilating and platelet aggregation inhibiting properties. Pharmaceutical compositions are described as are methods of use. Intermediates and processes for the preparation of the compounds of the formula (I) are described.
