Compositions, systems, and methods for providing smudge resistant and durable ink-jet images having good optical density are provided. Specifically, a system for printing durable ink-jet ink images can comprise a first ink-jet pen containing an ink-jet ink and a second ink-jet pen containing a fixer composition. The ink-jet ink can comprise a first liquid vehicle and a colorant. The fixer composition can comprise a second liquid vehicle, and from 0.5 wt % to 5 wt % of a cationic copolymer of an epihalohydrin and an amine. Upon overprinting or underprinting the fixer composition with respect to the ink-jet ink on a substrate, a durable image can be formed.

摘要:
The power train has a manual throttle controlled gas turbine engine having a high no load idle speed and a transmission having a low capacity fluid coupling and a variable capacity slipping friction clutch connected in parallel to the input of a multiratio gear unit for driving a vehicle. During engine idle with the vehicle stationary, when the gear unit is in neutral, the fluid coupling is unloaded to permit the engine to operate and drive the accessories at a high no load idle speed. When the gear unit is placed in a drive ratio, the fluid coupling is stalled loading the engine and reducing the no load idle speed to a regulated lower drive starting idle speed range, to reduce the inertia energy level for smooth drive starting clutch engagement and to maintain the engine output speed in a proper vehicle accessory operating idle speed range. When the throttle is increased from idle to initiate vehicle drive, in a minimal low throttle range, the engine torque and speed will increase in accordance with the fluid coupling stall torque characteristics, in a large middle throttle range, the torque capacity of the slipping friction clutch will increase proportional to the compressor discharge pressure of the as turbine engine and the engine output torque will increase with reduced engine output speed to provide normal drive initiating torque requirements and in a small maximum throttle range, full capacity non-slip engagement of the friction clutch will provide increased engine torque at zero engine output speed to maximum torque to meet maximum drive initiating torque requirements.

Dyes of formula (I) below are described. The dyes are useful as mid-green sensitizing dyes for photographic materials ##STR1## In the above formula, R1 and R3 are methyl or ethyl, at least one of R1 and R3 being methyl. R2 and R4 are substituted or unsubstituted C.sub.1 to C.sub.6 alkyl, provided that R2 and R4 are not both methyl. X1, X2, X3, and X4 are each independently methyl, methylthio, fluoro-substituted methyl or methylthio, or hydrogen, provided that at least one of X1 and X2 and at least one of X3 and X4 are not hydrogen. Y represents an ion as needed to balance the charge of the molecule. The dyes of formula (I) sensitize silver halide to light in the mid-green region of the spectrum.
