摘要:
Provided is an aqueous ink composition for a writing instrument which is excellent in a drying property of the drawn lines and a low temperature stability of the ink while inhibiting the pen tip from drying and which prevents the drawn lines from causing feathering and strike-through. The aqueous ink composition for a writing instrument described above contains at least a colorant, trimethylglycine, pentaerythritol, 10 % by mass or less of a water-soluble organic solvent, and water.

Provided is a mechanical pencil which is configured so that a rotatable cam is rotationally driven with an axis of the rotatable cam relative to a holder member stabled, and smooth operation of a rotational drive mechanism is ensured. The mechanical pencil includes a rotational drive mechanism 21 for driving rotationally a rotatable cam 23 according to writing pressure applied to a writing lead, and transfer rotational motion of the rotatable cam 23 to the writing lead. The rotational drive mechanism 21 includes a holder member 22 supporting the rotatable cam 23 so as to be rotatable, a first fixed cam 22c formed with a funnel-shaped inclined surface Fu and a second fixed cam 22d formed at an obtuse angle ± relative to an axial direction. Cam faces of an upper cam 23a and a lower cam 23b alternately meshing with the first and second fixed cams are formed along a conical inclined surface Cs.

Provided is an ink composition for an aqueous ballpoint pen making it possible to draw sharp and fine lines which are less likely to be blurred at an initial part of writing and are written smoothly and which are clear at stop, jump and sweep parts to provide beautiful characters. The ink composition for an aqueous ballpoint pen contains at least water and a colorant and having a dilatant fluid characteristic in at least a part of a region of a shear rate of 1 to 383 s -1 (25°C).

Provided by the present invention is a liquid cosmetic suited for a liquid cosmetic applicator using a brush or a pen feed as an applying means and suited for use in an eyeliner or an eyebrow, which has a good water resistance and is excellent in a skin adhesive property and which is free of a lustrous feeling and has a mat tone. The above liquid cosmetic comprises at least carbon black, water, 0.5 to 5 % by mass of a dispersant comprising a film-formable resin, 2 to 15 % by mass (in terms of a solid content) of a film-forming agent, 0.5 % by mass or less of a surfactant, and xanthan gum or a hydroxyethyl acrylate/acryloyldimethyltaurinato Na copolymer as a material for exerting an effect of a mat tone; a glossiness of the liquid cosmetic is 6.5 or less; and a viscosity thereof measured at a temperature of 25°C and a shear rate of 76.8 S -1 by means of an EMD type viscometer falls in a range of 10 to 270 mPa·s.

Provided is a manicure composition which is applied as a top coat on a manicure coated on a whole part of a nail and is turned into a transparent coating film after drying and which is top-coated to thereby provide the coating film with a satisfactory lasting property and endows it with glossy cracked patterns. The manicure composition is a cosmetic applied on a dried coating film of a nail cosmetic comprising at least nitrocellulose, acetic acid ester and a plasticizer, and it comprises at least water, an acryl resin emulsion having a glass transition temperature (Tg) of 50°C or higher and 2.5 to 11 % by mass of a film formation aid.
