摘要:
Disclosed is a liquid composition that, while maintaining good color developing properties and gloss, can realize good cleaning operation without staying of the liquid composition in a cleaning cap. The liquid composition is adapted for use with an ink composition for deposition on a recording medium and comprises a modified polyallylamine, a water soluble organic solvent, and water and is free from any colorant. The liquid composition and an ink composition each are deposited onto a recording medium to perform recording. A polymer comprising a recurring unit represented by formula (I) is used as the modified polyallylamine.

Disclosed are a process for the production of a low-molecular-weight allylamine polymer having a weight average molecular weight of 250 to 4,000 or an addition salt thereof, which comprises distilling a low-molecular-weight allylamine polymer solution to distill off unreacted monoallylamine, then, subjecting a residue to electrodialysis, and optionally carrying out acid treatment, a low-molecular-weight allylamine polymer having an ignition residue content of 5% by weight or less and a weight average molecular weight of 250 to 4,000, or an addition salt of a low-molecular-weight allylamine polymer having said properties, a water-resistance-imparting agent for use in an ink which comprises the above polymer or addition salt, and an ink composition comprising a colorant and the above water-resistance-imparting agent. According to the process of the present invention, a low-molecular-weight allylamine polymer improved in coloring and almost free of an inorganic salt or an addition salt thereof can be efficiently obtained. Further, the ink composition comprising the low-molecular-weight allylamine polymer or the salt thereof, provided by the present invention, not only has high water resistance but also is excellent in shelf life, and it is suitably used for inkjet recording.

A diving jacket includes a back-plate 22 and a pair of waist belt members respectively having circumferentially rear end regions fixed to the back-plate 22 by a means of associated connector plates 31. Rear end regions 37 of the respective connector plates 31 are formed with a plurality of dovetail tenons 51 or a plurality of dovetail grooves 52 arranged in vertical direction of the connector plates 31 so as to extend in parallel one to another and the back-plate 22 is formed with much more dovetail grooves 52 or dovetail tenons 51 than those formed in the connector plates 31 so as to be operatively associated with the dovetail tenons 51 or dovetail grooves 52 of the connector plates 31, respectively.
摘要:
A snorkel which includes a main conduit having an upper opening as well as a lower opening and a branch conduit branched from the main conduit. The branch conduit is formed at its top with a mouthpiece and a proximal end of the branch pipe is introduced into the main conduit, then curved toward the upper opening, and thereby eliminates swimmer physical fatigue due to purge diving use of the snorkel.
摘要:
Provided is a process for producing a copolymer of diallyldialkylammonium salt and a maleic acid which copolymer is free of residual monomers and polymerization initiator and hence stably exhibits excellent performances in various uses, and the process comprises polymerizing a monomer mixture comprising diallyldialkylammonium salt and maleic acid in the presence of persulfate as a radical polymerization initiator in water or a polar solvent, and completion of the polymerization-reaction, decomposing the radical polymerization initiator to produce a copolymer comprising diallyldialkylammonium salt constituent unit and a maleic acid constituent unit.

A mobile phone apparatus 10 is equipped with a camera module 36 including an image sensor (52), an AE evaluation circuit (60), etc. When a camera function is executed, an exposure is adjusted such that an exposure evaluated value is equal to an exposure target value, whereby, an AF controlling processing is executed. For example, when a shutter key is operated, the exposure target value is changed to an exposure target value for AF control being smaller than an exposure target value for normal photographing. Furthermore, a frame rate is increased such that the exposure evaluated value having a correlation to the frame rate is smaller than the exposure target value in response to the change of the exposure target value. Then, the AF controlling processing is executed on the basis of the image data every frame output from the image sensor (52) at the increased frame rate.
